1/4" Aluminum Plate

Aluminum is an alloy... so what is the definition of aluminum? Aren't there many kinds of aluminum? Can we melt down any kind of aluminum? What is considered aluminum, aircraft aluminum or junk heap aluminum? What does that mean we can't change the chemical composition, if there are many kinds of aluminum?
